In search for classification and selection of spare parts suitable for additive manufacturing: a literature review

This paper reviews the literature on additive manufacturing (AM) technologies and equipment, and spare parts classification criteria to propose a systematic process for selecting spare parts which are suitable for AM. This systematic process identifies criteria that can be used to select spare parts that are suitable for AM. The review found that there is limited research that addresses identifying processes for spare parts selection for AM, even though companies have identified this to be a key challenge in adopting AM. Seven areas for future research are identified relating to the methodology of spare parts selection for AM, processes for cross-functional integration in selecting spare parts for AM, broadening the spare parts portfolio that is suitable for AM (by considering usage of AM in conjunction with conventional technologies), and potential impact of AM on product modularity and integrality

Do Direct Payments Distort Producers' Decisions? An Examination of the Farm Security and Rural Investment Act of 2002

Do direct payments alter operators' acreage decisions? The authors use an event study with individual-level data in a panel-data setting to examine how an exogenous change in direct payments affects individual farmers' production decisions. They track changes in acreage across time and examine whether an exogenous, government implemented Act that allowed farmers to update base acres altered individual operators' acreage decisions. Results suggest that direct payments do change individual acreage decisions, ranging from approximately 44 to 78 acre increases (9 to 16% changes). Their results have no implications for aggregate production impacts. Copyright 2010, Oxford University Press.
